The world's most expensive streets

Hot spot: Yonge Street to Avenue Road.
Rent: $300 per square foot.
State of the market: You might not think of luxury when it comes to our neighbors up north, but Toronto is one of the fastest-growing markets, and Bloor Street, known as "Mink Mile," has suddenly hit the radar of luxury retailers. That could be because even though rents have increased 50% in the past year, they are still a relative steal, and tenants can pull in $1,500 to $4,000 per square foot in sales. Coming soon: a new Cartier store and Brooks Brothers, which has plans to open a 25,000-square-foot store.
